Topic: Why do we see no Northern lights/Auroras around the Sun? (Read 4053 times)

We observe Auroras in the Northern Hemisphere, and Auroras are caused by in short -

''The short answer to how the aurora happens is that energetic electrically charged particles (mostly electrons) accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light.''

Google search.

An effect observed by an interaction of the Earth's magnetic field.

It is also said that the Sun has an electromagnetic field,

We also observe light from distant stars,

So if the Sun has an electromagnetic field, why do we not observe any Auroras around the Sun from where other light sources are emitting towards the Sun?

The STEREO spacecraft are able to observe the solar flares on the Sun that produce the auroras, and also to see the Coronal Mess Ejection on its way from the Sun to the Earth. These CMEs produce the most dramatic auroras - sometimes even seen near the equator.

ar right thanks, what do these solar flares turn into when they vanish from observation?

Forget what jccc said. The aurora borealis is created by charged particles that are released from the sun and hit the earths magnetic field. All charged particles spiral around magnetic field lines and follow them to the poles. Charges that spiral around a field line are actually accelerating. Accelerating charged particles emit radiation. In this case the radiation is partially in the visible spectrum.

There's no reason to assume that this doesn't happen in the sun. When the sun emits a solar flare those particles are also charged and follow large loops. In essence that too is a sort of an Aurora. But no Aurora is "around" any body. The region its in is limited.

Thank you Pm, I have seen in a few videos a solar flare being cast into space then vanish rather than looping around back to the sun by gravity. What do these flares becomes,

I don't recommend wiki for leading edge topics, and some other articles only scratch the surface, but for some subjects itis quite good. You could try this, but be aware it mentions things you don't believe in!http://en.m.wikipedia.org/wiki/Solar_flare

Thank you for the answers, ''No, but it can dissipate - spread out so thinly that the effect is small.''

an effect as small as EMR?

or a CBMR?

or a plasma aether?

and why does the Sun not just dissipate like any other self respecting plasma?

As implied, it is very hard to contain a plasma (contained nuclear fusion research has been going for 50 years, and we still don't have a production-quality reactor).

However, the Sun has a powerful containment field - it's massive* gravitational field. This holds the plasma together, and provides the pressures at the center that can initiate and sustain nuclear fusion.

*Note: This is the vernacular meaning of "Massive", not the "Physics" definition.
